Improvement in faucets

E. MAX FASOLDT, on ALBANY, New YORK.

IMPROVEMENT IN FAUCETS.

Specification forming part of Letters Patent No. 166,197, dated August3, 1875; application riled December 4, 1874.

To all whom it may concern:

Be it known that I, E. MAX FAsoLn'r, of the city and county of Albanyand State of New York, have invented a new and Improved Faucet for Beer,Ale, and other liquids, of which the following is a full and exactdescription, reference being had to the accompanying drawing making partof this specification, which shows a longitudinal section of my faucet.

My invention relates particularly to faucets for drawing beer and otherfermented liquors;

and consists in constructing them substan' tially as herein shown anddescribed, having, as an integral part thereof, an air-pump for forcinginto the vessel containing the liquid and which, when moistened,partially acts as a valve to retard the flow of air into the pump belowthe piston, thereby aiding to fill this portion of the pump with liquidfrom the vessel.

As shown in the drawing, A is the body of the faucet, containing theoutlet'passage B. (l is the cylinder of the air-pump, near the lower endof which the outlet-passage B enters it. Preferably, I make it in onecasting with the body of the faucet, but it may be made separately, andattached to the body by any of'the well-known means. It has are-enforced band around its circumference, in line with the body of thefaucet, for the purpose of securing sufficient strength to protect itfrom injury while driving the faucet into its place. The re-enforce bandterminates in the head D for the purpose of receiving the blowsnecessary for driving the faucet in. E is an induction-valve for theadmission of air into, the cylinder of the air-pump, above the piston. Fis an eduction-valve, through which the air is forced from the air-pumpinto the tube G, which terminates at the inner end of the body of thefaucet, from whence it passes into the vessel containing the liquid. His the piston of the air-pump, having for its packing metallic ringslike those generally used in steam-engines; but, while I preferably usethis packing, any other kind may be used that is suitable for thispurpose. I is the rod to which the piston H is secured. It passes out ofthe cap J of the air-pump, through a stuffing-box, and terminates in thehandle K. L is the bottom head of the airpump, provided with adischarge-pipe, M. N is a disk of sponge or other porous material,interposed between the piston of the airpump and the discharge-pipe M,for the purpose of filtering the liquid passing through the faucet. Italso obstructs the flow of air into the lower portion of the pump,causing it to fill more readily with the liquid from the vessel.

The discharge of liquid through my faucet is effected by raising thepiston of the airpump, whereby the end of the outlet-passage B isuncovered, and the air contained in the cylinder of the pump, above thepiston, is forced into the vessel of liquid, thereby causing an equalquantity of fluid to pass into the cylinder, beneath the piston, which,by the downward stroke of the piston, is ejected from the cylinderthrough the discharge-pipe M. Passing in its course through the spongeN, it has allof its insoluble matter thoroughly filtered from it. By thedownward stroke of the piston the cylinder of the air-pump, above thepiston, is again charged with air, leaving it in condition for repeatingthe operation.

By injecting air under pressure into the vessel the beer or otherfermented liquor contained therein will retain its life until thecontents are entirely discharged,thereby remedying a serious eviloccasioned by admitting air through a vent-hole, as required when usingthe common faucet, whereby the liquor becomes dead and lifeless byreason of parting with its fixed air and gases.

I claim as my invention- 1. The combination of the faucet A with theair-pump G, when arranged as herein described, and in such manner thateach stroke of the piston H will reciprocally inject air into a vesselcontaining liquid, and eject an equal quantity ofliquid therefrom, asherein specified.

2. The faucet A, having the air-pump G and piston H arranged in relationto the air-passage G and outlet-passage B, and constructed to operate inthe manner and for the purpose herein specified.

3. The combination of the faucet A and airpump (J with the filteringmaterial N, substantially as and for the purpose set forth.
